Patent-e iii-troy Application filed July 20, 1911. Serial No. 633,680.

To all whom it may concern Be it known that I, CLAUDE V. Fouling, a: citizenof the United States, residing in the city of Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Sanitary Telephone-Mouthpieces, of which the fol-,'

lowing is a specification.

My invention in sanitery telephone mouthpieces relates to a removable lining which may be inserted in the mouthpiece of a telephone transmitter and which may be sold at a. sufliciently low price, as to be discarded after it has been used but once.

My invention has reference to attachments for telephone moutli'pieces which may be and in this connection, the object of myinvention is to provide a simple and effective means for preventing the spreading of disease, through infection between the difien entindividuals using e, common telephone mouth piece.

' The feature characteristic of my invention whereby I attain the object thereof, lies in the construction ofa. lining which may be readily applied to the inner Walls of a telephone mouth-piece as Well. as to the outer rim or edge thereof whereby any infections deposit or sediment which may he clinging to the inner surface of the telephone mouthpiece will be shielded by the said lining from an individual in the act of aspirating during. speech through the telephone mouth piece to which my improved shield or lining is applied.

In carrying out my invention 1. have pr ferred to employ paper or other inexpensive material. in the construction of these anti septic shields or hacteriehscrecns at e suf-- ficlcntly low cost to the user to promote lilo-L ernlit-y in their renewals. To afford the highest degree of efiiciency to these 'entisep tic shields, I prefer the construction beet adapted to lie nearly injcontect v1th the inner walls or exposed end of the usual form of telephonic transmitter mouth piece and such constructions as may be expecli-fl tiouslynienufactured by a mechzinicnl operation from lighterlnediuni grades of paper.

The construction referredto is depicted art of this specification, and which are to e ta'ken in connection with the appended invention; In these four form, to provide the in reference refer to like 'orter mouth piece constructed of J2 correlative descriptive matter, end th tinct features of novelty are referred to the claim at the conclusion of the tion. it-l1 reference to the drewingsl ienr i is a sectional elevetionel view "l.

and within the shell or lining C is perforated bottom corresponding to the bottom ll of the mouth piece A. I

".ihe shell C illustrated in the forms Figs. l, 2-, and 4 is constructed in two sections, an upper section O and'a lower section C be ing smaller in diameter than the section C. The section C is interfitted therewith and is united equatorially by telescopic, cnis call joint {3 -The purpose of forming the shell 6 in section C and C is to provide an outer wall which more approximately con forms to the inner andcorresponding surface or wall of the telephonicmouth piece A; the usual grades of paper are em- 3 pioyed which when otherwise constructed does not permit of the requisite degree of -.'.sl1aping in the process of manufacture, due its the nature of this material. resisting stretching. Upon examination of a mouth flyoiece of an ordinary telephone transmitter it will be noted that the same divergesoutfrom the inner end thereof in a curve, and notice e. straight line. By new 7 I solicit this, feet it is quite dilficult to com street an antiseptic guard of a. single piece of paper which wlllconform to the cur 'rilinear disposition of the mouth piece,- princi -ally because the paper-will not permit ic' stretching. This is readily compensated for by constructing the mouth piece new sections, having diiferent degrees of inclination so. that w on they-are secured 2} together 'equatorially and inserted into the v transmitter they will frictionally engage the or well of the latter suiticient to retain wice as a whole from displacement.

c. l. and *2 I have shown similarly cted bottoms These bottoms are d of grade of paper or other suitable which may be pressed to the form of llcwcup or dish having a suificlent width of the upturned edge or flange which designated a in the drawings, to present.

the necessary surface for properly securing it within the lower terminus ofthe section (l when the former material is employed av light grade of straw board. appears to posse'ss the requisite .degree of extensibility when moistened to permit of the required pressing to accomplish theend sought.

In Fi Q I have illustrated a construction for the ottom E which necessitates the use ofa more rigid material than in theotlier constructions referred to in which instance perforated bottom of bristol board, gelatin, celluloid or the like is forced into the section 0 so as to wed e itself into'the narrow bottom thereof; a ter which the bot tom edge designated c is spun over. It is obvious however, that the lower section C may be rolled or formed around the bottom E in the process of manufacture and fastened thereto with an adhesive material.

In Fig.6 I have illustrated a form where:

position from that illustrated in Figs. 1 or 2 and in this instance the flange 6 is con.-

tracted to conform to the diverging walls of the shell C and due to the resulting compression a'suitable joint may be made at the points of contact when a comparative light grade of paper is employed in its construction.

In Fig. 5 I have illustrated a form of shell 0 which may be readily constructed'of narrow tape or a ribbon of paper by winding the same spirally upon itself one or more times for each convolution of the paper strip, a suitable form being employed within the conical shell thus constructed to shape the walls thereof, after which a bottom E may be applied preferably cxteriorly to the lower extremity or truncated end of the conical shell in which instance the form of the bottom illustrated in Figs. 1 and 2 is employed.

In Fi 6 I have illustrated the form of shell or bacterial screen for the mouth piece A which may be formed by a spinning process when a. sufliciently yielding grace of paper is employed and suitably moistened to J en ure the requisite stretching and to stand the mechanical operation to be performed thereon. In this figure it will be observed that'the bottom E and the flange D are inte ralwith the walls of the shell C.

. "n the construction illustrated in Fig. 7 I have shown a form of shell G which may be formed on a mandrel in a similar manner to that illustratedin Fig. 6;. this may be constructed of a grade of paper not ossessing the degree of yield or extensibility of that demanded by the. construction illu.:- trated in Fig. 6, and to this end a suitable disk or blank of the material is plaited or folded radially in a suitable form or mold or it may he s no. to affect-the longitudinal formation of t e plaits or folds in order to provide the requisite conical formation. A

' bottom E illustrated in the dotted lines may be introduced interiorly or applied exteriorly as in Fig. 5, to stiffen or reinforce the erf'orated terminus of the structure.

In Figs, 2, ,3, 5, and,.'i', I have shown the flange D as being constructed of separate material from their corresponding shells and assembled thereon while in Figs. 1, 4, and 6, I have shown the flanges D to be integral parts of the shell C; the former construction is resorted to when the grade of.

material employed does notpermit of the requ1s1te amount of distortion which the latter construction necessitates in the proc- V ess of-constr'uetion.

In any ofthe formation of the shells or screens 0 and their correlative parts a suitable sizing or coating ofwax is a "ed interlorly and exteriorly to fill the poreslm'nd interstices of the material or other crevices,..

and to render the surfaces impregnable to bacteria or other infection: the aim. of the shell G being to form a bacterial screen to prevent the exit of disease germs which may gather on the inner surface of the mouth piece A either between the outer surface cf the lihing C and the inner surface of the mouth piece A and out over the edge of the latter or by transition or migration through.

the wall of the shell G or through any pore,

hole or crevice thereof, and m order to render the telephonic mouth piece still; fut ther aseptic by the use ofmy improved shell or screen I prefer to saturate the same ina sultable antiseptic preparation which at the same time will emlt an agreeable odor.

It is a purpose, in introduciu my invention to the public, to place in pu lie or other places a generous supply of my improved antiseptic shells or screens in either an aueieccs of Witnesses Pmzm SEEN, J. G.
